Then we can also build the > Objective-C front-end, and then start GNUstepping. What do you think about the attached diff? Is there a way to avoid multiple ‘map’s? What about the names of the packages? For example, ‘gcc-fortran’ is usually called ‘gfortran’, ‘gcc-go’ is called ‘gccgo’, etc. Should we use these names? How should we call ‘gcc-objc’, then? If you want to test any of the front-ends, don’t forget to set LIBRARY_PATH and LD_LIBRARY_PATH, like so: $ export LIBRARY_PATH=/nix/store/wmaxqx3p658v2yqjv00mss2shvn23h7a-glibc-2.18/lib $ export LD_LIBRARY_PATH=/nix/store/kvhg0fszagsx5y80sq79bkmb7yqvjfmd-gcc-go-4.8.1/lib Notes: 1. The Go front-end requires ‘-g’ (see [1]). 2. “GFORTRAN guesses the source code formatting based on the file extension. For .f90 files, it will assume it's working with FORTRAN 90 source code and use free formatting rules. For .f and .for files, it will assume the file is F77 source code and use fixed formatting rules.” [2] 3. If you want to compile Objective-C or Objective-C++, pass ‘-x <lang>’ to ‘gcc’. 4. The Ada front-end requires GNAT [3] (see [4]). 5. Not sure why the Java front-end fails: libtool: link: ( cd ".libs" && rm -f "libquadmath.la" && ln -s "../libquadmath.la" "libquadmath.la" ) make[3]: Leaving directory `/tmp/nix-build-gcc-java-4.8.1.drv-0/build/i686-pc-linux-gnu/libquadmath' make[2]: Leaving directory `/tmp/nix-build-gcc-java-4.8.1.drv-0/build/i686-pc-linux-gnu/libquadmath' make[1]: Leaving directory `/tmp/nix-build-gcc-java-4.8.1.drv-0/build' make: *** [all] Error 2 phase `build' failed after 2229 seconds note: keeping build directory `/tmp/nix-build-gcc-java-4.8.1.drv-0' builder for `/nix/store/wlqwyy9k9mbl3wpy9jq08k91qq23f4kp-gcc-java-4.8.1.drv' failed with exit code 1 @ build-failed /nix/store/wlqwyy9k9mbl3wpy9jq08k91qq23f4kp-gcc-java-4.8.1.drv - 1 builder for `/nix/store/wlqwyy9k9mbl3wpy9jq08k91qq23f4kp-gcc-java-4.8.1.drv' failed with exit code 1 guix build: error: build failed: build of `/nix/store/wlqwyy9k9mbl3wpy9jq08k91qq23f4kp-gcc-java-4.8.1.drv' failed [1] http://gcc.gnu.org/bugzilla/show_bug.cgi?id=57194 [2] http://ubuntuforums.org/showthread.php?t=853105 [3] https://www.gnu.org/software/gnat/ [4] http://gcc.gnu.org/ml/gcc/2007-11/msg00091.html
